I don't if any US folks on here will have heard of them (maybe through E-Bay), but this mob 23rd Century, whom I don't believe are strictly legit, have been selling many trashy films through pound shops.

So far I've been able to pick up Fulci's Conquest, Italian Over the Top rip off Atomic Cyborg, really awful zombie nazi flicks The Chilling and some film called Jungle Hell that I haven't found the courage to watch yet.
